SIMEON OOON, OF ITHAOA, NEW YORK.

BURGLAR-ALARM.

Specification of Letters Patent No. 18,236, dated September 22, 1857.

To all whom it may concern:

Be it known that I, SIMEON Coon, of Ithaca, Tompkinscounty, New York, have invented an Improvement in Burglar- Alarms; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The pistol barrel A may be constructed of any metal suitable for firearms and of any desired form, but for convenience of manufacture by turning lathes I have adapted my improvement so that a cylindrical form may be used. To this barrel A, I attach at the muzzle the gimlet formed screw B to work upon a pivot and to be affixed to the barrel opposite the spring E. The stirrup D I attach to the barrel at points m and n, opposite each other and at a distance from the nipple 0 suflicient to give to the spring length of stroke.

E is a double spring with its ends of equal length to be place under stirrup D. Then sprung it (spring E) lies in a position hori zontal with the barrel and when set for action it stands at right angles with the barrel and on its centers, being held in this position by a notch cut in the barrel under the centers. A slight force applied to the 0pposite end of this spring E, will throw it from its center and bring this opposite end as a hammer down upon the nipple 0.

For use, the gimlet screw B being set into the door casing at proper inclination the muzzle of barrel A, will point through the opening made between the door and easing as the door opens, and at the same time the opening door will strike the hammer end of spring E, and bring it down upon the nipple 0, thereby discharging the piece and giving the alarm.

\Vhat I claim as my invention and desire to secure by Letters Patent is The combining the spring E and hammer E in one piece and acting on a stirrup as above described and constructed.
